Application filed August 21, 1914. Serial No. 857,849.

To aZZ whom it may concern 1 Be it known that I, GEORGE W. CoMnE, a citizen of the United States of America, and a resident of WVaterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Corner-Fastenings for Bedsteads, of which the following is a specilication.

My invention relates to improvements in corner-fastenings for bedsteads, and the object of my improvement is to provide detachable means for securing the ends of the side bars of the bed-frame to the cornerposts thereof, suitably designed particularly for. use for bedsteads having tubular metal corner-posts. This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which:

Figure 1 is a central vertical section of a portion of a tubular metal corner postfor a bedstead, showing a side-bar detachably connected thereto by my improved fastening means. Fig. 2 is an elevation of said post, showing said fastening means in en elevation and the side-bar in cross section. Fig. 3 is a central vertical longitudinal section of said corner post, taken at a right angle to'Fig. 1, with said side-bar and fastening means removed, and showing the reinforcing body mounted within said post. Fig. 1 is a plan view of said device, with said corner-post taken in cross section.

5 is an elevation of the side-bar fastening means which is opposite to that shown in said Fig. 1.

Similar numerals of reference denote cor responding parts throughout the several views.

My improved device is adapted for use in securing detachably any bracket-armor bar to any tubular structure, but is particularly adapted for use in removably securing the side-bar of a bedstead to a tubular corner post therefor.

In the drawings, the numeral 1 denotes a portion of the tubular metallic corner-post for a bedstead, provided with a relatively short longitudinal slot 19. v

The numeral 12 denotes a trough-shaped bar bifurcated at its upper end to furnish two parallel forks or members 13 and 14:, which lie along the opposite vertical edges of the slot 19 in said post 1, covering a small portion of the lower part of said slot, and

extendingfor a short distance above the upper end of the slot. The parallel walls at the inner sides of said members 13 and 1-1 are thus continuous with and lie in the same lanes as the inner vertical walls of said slot 19. The lower and wider part of the body 12 is secured to the inner Wall of said post 1 by means of a bolt 20 a ndnut 21.

The members 13 and 14: are similarly secured to the post by means of bolts 15 and nuts 16. l

Referring now toFigs. 1, 2, 4 and 5, the numeral. 2 denotes one end of a side-bar of angular cross section. A plate 3 is secured to the extremity of said bar by means of rivets 1, and has parts 5 of its upper and lower longitudinal. edges bent over in the same direction on one side to clamp said angle-bar 2 between them." Said plate 3 has an integral extension 8-9 beyond the end of said side-bar 2, the part 8 being narrower than the outer part 9, and having like squared grooves in its upper and lower parts to fit at 10 over the squared grooved seat in the body 12 between the members 13 and 14 1 thereof. The wider part 9 has like upward and downwardly extending ends 11' curved at their outer angles. Integral with said plate 3 are upwardly and downwardly extending portions 6 and 7, respectively, in which the uppermost projection 6 is longer. The said projections have on their outer edges the curved parts 17 and 18 respec' tively, the functions of which will be described.

To secure the side-bar 2 to the tubular 70st 1, the hookedpart 9 of the plate 3 is inserted into the slot 19fof the post, and then moved downwardly to have its neckpart 8 seated at 10 uponthe squared seat in the bifurcated body 12. In this position the neck 8 closely engages the inner walls of the forks 13 and 14, while the curved parts 17 and 18 of the projections 6 and 7 enter and engage'the inner walls of the slot 19. The edges of said projections without said curved parts are straight and alined and engage the outer wall of the post 1 above and below the ends of said slot 19, thus locking the connection against up or down swinging movements, while the wide engaging-means for the part 8 between the forks 13 and 14, and the parts 17 and 18 between the walls of said slot eflectually prevent lateral movement in the connected parts of the joint. The hook 11 of the part 9 is disengaged from the post by merely raising same ver tically a short distance, and then Withdrawing it from the slot 19. The connectingmeans attached to the bar 2 is reversible as the upper hook 11 may be engaged similarly when reversed. A small amount of clearance is provided between the main body of the plate 3 and each hook 11 by widening the squared groove therebetween outwardly, while the curved outer angles of said hooks facilitate entrance of the same into said slot.

Having described my invention, what I claim as new, and desire to secure by Le ters Patent, is:

1. A hollow body having a longitudinal slot, a bar having a trifoliate extremity the middle leaf and a part of each of the other leaves of which enter and engage the walls of said slot and the inner part of the body.

2. A hollow body having a longitudinal slot and containing in its interior detachably-secured engaging-means, a bar having a trifoliate end. the middle leaf of which enters and engages the slot and said engagingmeans, and the other leaves of which engage the outer wall of said body.

3. A hollow tube having a longitudinal slot, a bar having a trifoliate extremity, a bifurcated body secured to the inner wall of said tube to have its interspace over the said slot, the middle leaf of said bar being transversely grooved on its under side, and passed through said slot, with the grooved part of said leaf detachably engaged about the latter at its bifurcation.

4. A hollow tube having a longitudinal. slot, a bar having a plate attached to one end to project therefrom, said plate having a longitudinally extending projection provided with like oppositely-projecting lugs to furnish like squared grooved seats between the lugs and the main body of the plate, a body having a squared groove, seated in and detachably secured to the inside of the tube with the groove alined with part of said slot, the said plate projection being detachably inserted in said slot and said alined groove with one of said lugs and the squared seat adjacent thereto engaged with the inner surface of said body.

5. A hollow tube having a longitudinal slot, a bar having a plate attached to one end to project therefrom, said plate having a longitudinally extending projection provided with like oppositely-projecting lugs to furnish like squared grooved seats between the lugs and the main body of the plate, a body having a squared opening, seated in and detachably secured to the inside of the tube with a squared end of the opening extending across the said slot and the opening thence alined with said slot, the said plate projection being detachably mounted in said slot and opening with its squared seat fitted upon the squared end of the said opening and one of said lugs engaged with the inner face of the said body, the said plate having upwardly and downwardly-extend ing projections adapted to engage the outer wall of said tube longitudinally when the first mentioned projection is mounted in said slot.

6. A hollow tube having a longitudinal slot, a bar having a plate attached to one end to project therefrom, said plate having a longitudinally extending projection provided with like oppositely-projecting lugs to furnish like squared grooved seats between the lugs and the main body of the plate, a body having a squared opening, seated in and detachably secured to the inside of the tube with a squared end of the opening ex tending across the said slot and the opening thence alined with said slot, the said plate projection being detachably mounted in said slot and opening with its squared seat fitted upon the squared end of the said opening and one of said lugs engaged with the inner face of the said body, the said plate having upwardly and downwardly-extending projections adapted to engage the outer wall of said tube longitudinally when the first mentioned projection is mounted in said slot, and each of said last-mentioned projections having a portion extending into said slot to engage the inner walls of the latter.
